Abstract

A container for mixing two fluids includes: a container, a pouring cylinder; an upward facing step portion, a cap whose inner circumferential surface is screwed onto an outer circumferential surface of the pouring cylinder, a small container placed on an inner side of the cap; a cuttable first sheet that forms a bottom surface of the small container, a removable cylinder provided at a bottom end of the cap and interposed between the cap and the upward facing step portion, and a first cutter that is provided on the container so as to face a bottom surface of the small container that is placed on the inner side of the cap. The small container is made to approach the first container, and the first sheet is then cut by the first cutter.

First claim

The invention claimed is:

1. A container for mixing two fluids comprising:
a container configured to contain one of the two fluids;
a pouring cylinder that is provided extending upwards on a top portion of the container;
an upward facing step portion that is formed on the container so as to be positioned below the pouring cylinder;
a cap that is removably attached to the pouring cylinder;
a male threaded portion that is formed on an outer circumferential surface of the pouring cylinder;
a female threaded portion that is formed on an inner circumferential surface of the cap and that is engaged with the male threaded portion to attach the cap to the pouring cylinder;
a small container that is placed on an inner side of the cap and is configured to contain an other of two fluids;
a cuttable sheet that forms a bottom surface of the pouring cylinder;
a removable cylinder that is provided at a bottom end of the cap and is interposed between the cap and the upward facing step portion, and that is removed from the cap prior to the cap being screwed down onto the pouring cylinder; and
a cutter that is provided on the cap so as to face the bottom surface of the pouring cylinder, wherein
the pouring cylinder is made to approach the cutter as a result of the cap being screwed down onto the pouring cylinder,
the sheet is cut by the cutter circularly from a position where the cutter initially began to cut the sheet, and
before the cutter arrives the position again, the cutter is configured to contact an arm provided on the pouring cylinder in a circumferential direction such that rotation of the cap with respect the pouring cylinder is restricted in a direction that the cap is screwed down.

2. The container for mixing two fluids according to claim 1 , further comprising:
a cuttable another sheet that forms a bottom surface of the small container;
an another cutter that is provided on the container so as to face a bottom surface of the small container that is placed on the inner side of the cap; and
a stopper that that is provided on the cap and is configured to restrict a rotation of the cap with respect to the pouring cylinder, wherein
the small container is made to approach the another cutter as a result of the cap being screwed down onto the pouring cylinder,
the another sheet is cut by the another cutter circularly from a position where the another cutter initially began to cut the another sheet, and

before the another cutter arrives the position again, the stopper is configured to contact an arm provided on the pouring cylinder in a circumferential direction such that rotation of the cap with respect the pouring cylinder is restricted in a direction opposite to a direction that the cap is screwed down.

3. The container for mixing two fluids according to claim 2 , wherein
the container is provided with a container body, an aperture portion that is provided extending upright from a top portion of the container body, and a pouring component that has the pouring cylinder and is fitted onto the aperture portion such that it is unable to pivot, and
the pouring cylinder is made to extend upright from the top portion of the container as a result of the pouring component being fitted to the aperture portion, and
the another cutter is provided on the pouring component so as to protrude upwards.

4. The container for mixing two fluids according to claim 3 , wherein
the pouring component is provided with:
a flange-shaped apex plate that is provided at a bottom end of the pouring cylinder; an outer cylinder that hangs vertically down from the apex plate; an inner cylinder that is placed on an inner side of the outer cylinder and hangs vertically downwards from the apex plate, and an inward facing flange that is provided so as to protrude from the apex plate onto an inner side of the pouring cylinder, and
the another cutter is provided on the inward facing flange so as to protrude upwards, and
the pouring component is fitted to the aperture portion such that the aperture portion becomes inserted between the outer cylinder and the inner cylinder.

5. The container for mixing two fluids according to any of claims 1 through 4 , wherein
the cap is provided with an apex wall, an outer circumferential wall that hangs vertically downwards from the apex wall, and an inner circumferential wall that is placed on an inner side of the outer circumferential wall and hangs vertically downwards from the apex wall, and
the small container engages with an inner side of the inner circumferential wall of the cap, and
the cap is screwed onto the pouring cylinder so that the inner circumferential wall is inserted on an inner side of the pouring cylinder.

6. The container for mixing two fluids according to claim 5 , wherein
the small container is provided with an apex wall, a circumferential wall that hangs vertically downwards from the apex wall, and an outward facing flange that is provided so as to protrude outwards from the bottom end of the circumferential wall, and
a top surface of the outward facing flange is adhered to a bottom end surface of the inner circumferential wall of the cap, and an interior of the inner circumferential wall is tightly sealed by the small container.

7. The container for mixing two fluids according to claim 1 , wherein
the sheet is joined to a bottom end surface of the pouring cylinder by insert molding.

8. The container for mixing two fluids according to claim 1 , wherein
the sheet is adhered to the bottom end surface of the pouring cylinder.

9. The container for mixing two fluids according to claim 1 , wherein
the container is provided with a container body, an aperture portion that is provided extending upright from a top portion of the container body, and a pouring component that has the pouring cylinder and is fitted onto the aperture portion such that it is unable to pivot, and
the sheet is formed integrally with the bottom end surface of the pouring cylinder when the pouring component is molded.

10. The container for mixing two fluids according to claim 1 , wherein
an end surface of the sheet is covered by the bottom end portion of the pouring cylinder by insert molding.

11. The container for mixing two fluids according to any of claims 1 through 4 , wherein
the small container is provided with an apex wall and a circumferential wall that hangs vertically downwards from the apex wall, and
the apex wall and the circumferential wall of the small container are formed by thickly stacking a plurality of membranes having barrier properties, and
the another sheet that forms the bottom surface of the small container is formed by stacking a plurality of membranes having barrier properties.

12. The container for mixing two fluids according to claim 1 , wherein
the sheet is formed by stacking a plurality of membranes having barrier properties.

13. The container for mixing two fluids according to claim 2 , wherein
the another cutter is provided on the bottom end of an inner cylinder that hangs downwards from the pouring cylinder via the arm, and
the stopper is provided on the bottom end of an inner circumferential wall of the cap so as to be adjacent to the cutter, and
after the another sheet and the sheet have been cut circularly, any pivoting of the cap in either the forward or reverse direction is obstructed as a result of the arm being positioned between the cutter and the stopper.

14. The container for mixing two fluids according to claim 13 , wherein
the stopper is a projection that protrudes downwards from the bottom and surface of the inner circumferential wall,
the projec
